Answer:

x = 5°

Step-by-step explanation:

The marked angles are "alternate exterior angles," hence congruent.

2x +90° = x +95°

x = 5° . . . . . . . . . . . . subtract (x+90°) from both sides

3tenths - 3 twentieth

lakkis [162]

Answer:

0.15

Step-by-step explanation:

Given expression

3 tenths- 3 twentieth

⇒

$=\frac{3}{10} -\frac{3}{20} \\=\frac{6}{20} -\frac{3}{20}\\=\frac{6-3}{20} \\=\frac{3}{20} \\=0.15$

Therefore value of given expression is 0.15

If y varies directly as x, and y = 42 as x = 6, find y for the x-value 3

mojhsa [17]

Y=42 Y=?
X=6 X=3

cross multiply
so 42times3=6timesY
126=6Y
Y=126 divided by 6

Find the Total Surface area of a Pyramid. Its base is a regular hexagon 4cm on a side. its height is 8 cm. Round off to nearest

oksano4ka [1.4K]

Answer:

The total surface area of a regular hexagonal pyramid is 146.2 cm².

Step-by-step explanation:

The base is a regular hexagon 4cm on a side. its height is 8 cm.

The total surface area of a pyramid with regular hexagon base

$A=\frac{3\sqrt{3}}{2}a^2+3a\sqrt{h^2+\frac{3a^2}{4}$

Where, a represents the base edge and h represents the height of the pyramid.

The area of given regular hexagonal pyramid is

$A=\frac{3\sqrt{3}}{2}(4)^2+3(4)\sqrt{(8)^2+\frac{3(4)^2}{4}$

$A=\frac{3\sqrt{3}}{2}(16)+12\sqrt{64+12}$

$A=24\sqrt{3}+12\sqrt{76}$

$A=146.182794027$

$A=146.2$

The total surface area of a regular hexagonal pyramid is 146.2 cm².
